Description
Technical field
The utility model belongs to road field, and in particular to a kind of new-type pavement structure for being adapted to Permafrost Area.
Background technology
China's permafrost distribution is wide, about 2,150,000 square kilometres of the gross area, and ever-frozen ground heat endurance is poor, to external world
Temperature change is very sensitive, most important for protection of permafrost, raising road structure stability using rational road structure.And
In Permafrost Area, cause road institute destroyed through regional thermal balance by the making of bituminous paving, cause frozen earth stable
Property destruction and degeneration, in turn resulting in road there is thaw collapse deformation, and the disease such as crack has a strong impact on vehicle pass-through, and restriction lands
Area's economic development, simultaneously because road damage often causes secondary destruction to frozen soil environment, forms vicious circle.
Existing air pipeline based structures, its ventilation pipe diameter is big, and arrangement spacing is big, and is arranged at roadbed bottom, distance
Actual thermal source far causes actual radiating efficiency relatively low, and large aperture pipeline due to summer hot blast pouring into often turn into second
Thermal source, while larger spacing easily makes pipeline enclosure radiating uneven, causes temperature field to make a variation, and is unfavorable for protection and the road of frozen soil
Stabilization.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide one kind to be adapted to Permafrost Area
New-type pavement structure, solve tradition ventilation pipeline base cooling effect it is poor, the low problem of stability, raising radiating efficiency it is same
When take into account structural stability and construction workability.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that being achieved：
A kind of new-type pavement structure for being adapted to Permafrost Area, from top to bottom including top course, sub-surface and
Roadbed, multiple aeration structures are equipped between described sub-surface and roadbed along road direction, and each described aeration structure is equal
Along having a lot of social connections, direction is extended to outside sub-surface, and described aeration structure is block, along the side of having a lot of social connections on each described aeration structure
To the air vent for being uniformly provided with multiple insertions, the two ends of described air vent are provided with temperature control automatic valve.
Described aeration structure is rectangular blocks.
Described air vent is circle.
GSZ is provided between described sub-surface and aeration structure.
Each aeration structure is provided with 3~5 air vents, and described air vent primary concreting is formed.
Tangent close-packed arrays between described multiple aeration structures.
A diameter of 10~50cm of described air vent.
Wall thickness between described air vent is 10~15cm.
The following technique effect of the utility model：
(1) the utility model mainly lays aeration structure by under sub-surface, can improve the radiating of pavement structure
Ability, has good specific aim to Frozen Ground Area asphalt pavement structure heat build-up phenomenon.
(2) crack reflection is to top course between the GSZ that the utility model is set can avoid ventilation body, it is ensured that
The stability of road structure；Temperature control automatic valve is by detecting that temperature outside is closed come the opening of control valve in roadbed
Close, it is to avoid the heat in summer air flow to roadbed frozen soil part, while can also evacuate the heat of winter road vehicles generation.
Brief description of the drawings
Fig. 1 is pavement structure profile of the utility model along direction of having a lot of social connections.
Fig. 2 is pavement structure profile of the utility model along road direction.
The implication of each label is in figure：1- top courses, 2- roadbases, 3- aeration structures, 4- GSZs, 5- roads
Base；
(3-1)-air vent, (3-2)-temperature control automatic valve.
Explanation is further explained in detail to particular content of the present utility model below in conjunction with accompanying drawing.
Specific embodiment
Specific embodiment of the utility model given below is, it is necessary to explanation is that the utility model is not limited to following tool
Body embodiment, all equivalents done on the basis of technical scheme each fall within protection domain of the present utility model.
Aeration structure of the present utility model 3 is placed under sub-surface 2, can reduce sub-surface thickness, reduces cost, ventilation
Structure 3 is closely coupled, increased the ability of radiating, and improves the stability of road structure.
Embodiment：
Defer to above-mentioned technical proposal, as shown in Figure 1 to Figure 2, the present embodiment provides a kind of Permafrost Area that is adapted to
New-type pavement structure, from top to bottom including top course 1, sub-surface 2 and roadbed 5, wherein top course 1, the and of sub-surface 2
Roadbed 5 is conventionally designed, and multiple aeration structures 3 are equipped between described roadbase 1 and roadbed 5, can be had
Targetedly the heat that dark-coloured pavement is gathered is dispersed, so as to maintain the thermal balance of Permafrost Area.
Each aeration structure 3 and the tight arranged tangential of adjacent aeration structure 3, each aeration structure 3 prolong along direction of having a lot of social connections
Extend outside sub-surface 2, described aeration structure 3 is the rectangular blocks of cast, edge on each described aeration structure 3
Direction of having a lot of social connections is uniformly provided with three circular vent 3-1 of insertion, and circular vent ventilates more smooth；Aeration structure
Air vent 3-1 primary concretings on 3 are formed；The two ends of air vent 3-1 are provided with temperature control automatic valve 3-2, for automatically controlling
The opening and closing of aeration structure.
So, when summer roadbed external temperature is higher, temperature control automatic valve 3-2 is closed, the heat in summer air can be avoided
Amount flow to roadbed frozen soil part, and frozen soil environment is damaged；Winter roadbed external temperature is relatively low, and what road vehicles were produced
Heat transfer opens temperature control automatic valve 3-2 to sub-surface 2, evacuates the heat in roadbed, protects frozen soil environment.
In the present embodiment, air vent 3-1 is three, a diameter of 40cm of air vent 3-1, and the wall thickness between air vent is
12cm, spacing is 2.15m between the axis of each two ventilation body, and the size of these distances is to meet structure thermal diffusivity and steady
The relatively figure of merit obtained on the basis of qualitatively.
Another scheme is same as Example 1, differs only in：It is provided between described sub-surface 2 and aeration structure 3
GSZ 4, crack reflection is to top course between can avoiding ventilation body, it is ensured that the stability of road structure.
